VETERINARY.OPERATING-TABLE.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed December 27,1905- Serial No- 293,543.

T aZZ whom it may concern.-

Be it known that I, CARL CozIER, a citizen of the United States, and a resident of Bellingham, in the county of Whatcom and State of Washington, have invented certain new and useful Improvements in Veterinary OperatingTables, of which the following is a specification.

My invention relates to an improvement in veterinary operating-tables; and it consists of an improved gear by means of which the table-top can be easily revolved throughan angle of ninety degrees and automatically retained in any stage of the revolution.

Referring to the one sheet of drawings forming a part of this application, Figure 1 is a side elevation of a veterinary operatingtable fitted with my device, and Fig. 2 is a plan view of the same.

Similar characters refer to similar parts in the two views. A, B, C, D, E, F, and G are the several members of the table-stand, portions of which are removed in Fig. 1, and H is the table-top, rigidly-attached to beams J J. 1 is ahorizontal shaft passing through the lefthand ends of the upper rails C C of the table-stand. This shaft also passes through two beams, to which the planks forming the table-top are fastened. The table-top is so hung on the shaft 1 that it may revolve from an upright osition, as shown in Figs. 1 and 2, to a horizontal position, as indicated in dotted outline H in Fig. 1, when it lies on to of the table-stand. Segmental ears 8 an 9 are rigidly attached to the cams of the top referred to concentric with shaft 1. Horizontal shaft 2 is parallel with shaft 1 and is supported in boxes 15 16, fastened to members A A of the table-stand. Shaft 2 has keyed to each end spur-gears 6 and 7. Shaft 2 occupies such a position that spur-gears 6 and 7 may mesh with segmental gears 8 and 9, respectively. Shaft 2 has keyed to it at a point midway between the spur-gears worm-Wheel 5. At. 'ri ht angles to shafts 1 and 2 is horizontal s aft'3, retained in boxes 13, 14, and 15 on members E,

r F, and G, respectively. Rigidly attached to shaft 3 is worm 4, so situated as to engage with worm-wheel 5. Set-rings 11 and 12 on shaft 3 revent end movement of this shaft. The rig t-hand end 3 projects beyond the 'the fastening devices referred to.

table-stand and is squared to receive the removable crank 10. I

Now by turning crank 10 power is transmitted through the worm and worm-wheel to the spur ears and thence to the segmental gears, and t e top H is' revolved through the angle of ninety degrees as desired. Furthermore, because of the worm 4 and worm-wheel 5 in this train of gears the table-top cannot be forced into any other position except by turning the crank 10. Hence-the presence of the worm and worm-wheel in the train of' gears causes the table-top to be automatically locked in any desired part of the are through which it may revolve about shaft 1. With this device are hopples, straps, and ropes for securely fastening an animal to the ta le-top; but as I do not claim them as a art of this invention they are not illustrated in the drawings.

In using the device the table-top is brought to the vertical position shown in Figs. 1 and 2 by revolving the crank 10. Then the animala horse, for instance-is caused to stand by the side of the table-to when he is securely fastened to the same y means of Then by turning the crank 10 the table-top H with the horse fastened to the same is brought from the vertical position to a horizontal position i on top of the table-stand or left at any angle of inclination desired between these two positions. Because of the worm and wormwheel it will be securely locked in any of these positions until the crank is again turned.

Thus one person unaided can safely operate I this device.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with a suitable, supporting-frame, of a veterinary operating-table hinged to a horizontal rod, which is retained in suitable bearings rigidly attached to said supporting-frame; a segment of a gear rigidy attached to said table and concentrlc with said rod; a horizontal shaft parallel to said rod and supported in suitable bearings which are rigidly attached to said supportingframe; a spur-gear rigidly attached to said shaft and meshing in said segment of a gear; a Worm-wheel rigidly attached to said horizhntal shaft; wdriving-shaft,iatmight angles with said-horizontal shaft, which is supported in bearings rigidly attached to said supportlng-frame, and t0=0ne end of iwhichiisirigidlyv attached a Worm enmeshed in said wormwheel, while to the other end is fitted amemovable crank.
